Optics Express
|April 4, 2024
Summary
Periodic edge dislocation (PED) effectively manipulates orbit-induced localized spin angular momentum (OILS). The study shows PED controls longitudinal and transverse OILS by adjusting its period relative to the vortex topological charge.
Area of Science:
- Optics and Photonics
- Condensed Matter Physics
- Quantum Information
Background:
- Orbit-induced localized spin angular momentum (OILS) is crucial for optical applications.
- Controlling OILS is essential for advanced optical systems.
Purpose of the Study:
- To investigate the use of periodic edge dislocation (PED) for manipulating OILS.
- To analyze the tight focusing characteristics of vortex beams with PED.
Main Methods:
- Introducing PED into a tight focusing system.
- Analyzing radially and linearly polarized vortex plane beams with PED.
- Examining the relationship between PED period and vortex topological charge.
Main Results:
- PED provides a simple and effective method for controlling OILS.
- Longitudinal OILS is maximized when PED period differs from topological charge by 1.
- Transverse OILS is maximized (longitudinal minimized) when PED period equals topological charge.
Conclusions:
- PED offers a practical approach to tune OILS in optical systems.
- Findings enhance understanding of optical orbit-spin coupling mechanisms.

01:23Atomic Nuclei: Nuclear Relaxation Processes
651
In the absence of an external magnetic field, nuclear spin states are degenerate and randomly oriented. When a magnetic field is applied, the spins begin to precess and orient themselves along (lower energy) or against (higher energy) the direction of the field. At equilibrium, a slight excess population of spins exists in the lower energy state. Because the direction of the magnetic field is fixed as the z-axis, the precessing magnetic moments are randomly oriented around the z-axis.

01:03Atomic Nuclei: Nuclear Spin State Overview
938
NMR-active nuclei have energy levels called 'spin states' that are associated with the orientations of their nuclear magnetic moments. In the absence of a magnetic field, the nuclear magnetic moments are randomly oriented, and the spin states are degenerate. When an external magnetic field is applied, the spin states have only 2 + 1 orientations available to them. A proton with = ½ has two available orientations. Similarly, for a quadrupolar nucleus with a nuclear spin value of...

10.9K
A system's total angular momentum remains constant if the net external torque acting on the system is zero. Examples of such systems include a freely spinning bicycle tire that slows over time due to torque arising from friction, or the slowing of Earth's rotation over millions of years due to frictional forces exerted on tidal deformations. However in the absence of a net external torque, the angular momentum remains conserved. The conservation of angular momentum principle requires a...

1.1K
An applied magnetic field causes loosely bound π-electrons in organic molecules to circulate, producing a local or induced diamagnetic field over a large spatial volume. As the molecules tumble in solution, the field generated by π-electrons in spherical substituents results in a zero net field. However, the net field generated by π-electrons in non-spherical substituents is not zero. The effect of this induced field depends on the orientation of the molecule with respect to B0,...
